  • Port Permissions

    From Mickey@VERT/CORSYS2 to All on Sunday, January 26, 2025 19:10:15
    I have just installed 3.20c on a Pi. The build went alone nicely and the system is mostly working. My issue:

    I execute sbbs with sudo and (according to what I've read) then hand access back to sbbs:sbbs after all the ports are loaded. This works great until ports 11 and 18 are called during operation and of course, access is denied. This does'nt seem to affect the bbs too much but I'd like to correct it (if I can).

    ufw is off and these ports are set-up to forward to the Pi. How do I fix this?

    Thanks,

    Why would access be denied?

    Rather than using sudo, consider using setcap instead:

    Most of the default TCP ports that sbbs tries to bind are privileged (i.e. < 1024), so I'm not clear why ports 11 and 18 would be special. Maybe they're just already bound to other services?

    This wiki entry helped I think, at least so far. I followed your direction, re-booted the Pi and it seems to be working.

    Thanks for the direction. :-)
